ERROR_IPSEC_MM_FILTER_NOT_FOUND
ERROR_IPSEC_MM_FILTER_NOT_FOUND (0x000032CF) A management operation referenced a Main Mode filter that is absent from the active configuration. This often follows policy replacement, a stale deployment identifier, or a mismatch between local and domain policy stores.
What to check
- List the current Main Mode rules and verify the filter identifier used by the tool or deployment script.
- Confirm that the expected Group Policy Object is applied to the computer and has not been superseded by a newer policy.
- Do not infer that IPsec negotiation is broken solely from this management error; verify active security associations separately.
